For Fans of The Good Wife: Alicia's Gorgeous Red Dress Tonight Is by Lanvin

The Chicago Shamrock Dinner is tonight! That only means something if you watch The Good Wife—and if you do, you’ll love tonight’s episode. Not only will the plot climax at the Shamrock Dinner, with the help of guest star Matthew Perry, the dinner itself will be a memorable black-tie moment for TV, according to costume designer Daniel Lawson. “It’s very stately affair and setting,” said Lawson. “And so I chose Alicia Florrick’s [Julianna Margulies] gown to be very stately. It was really fun to shop for and it was the first dress Julianna put on. When she did, she said, ‘This is it!’” The two-toned piece he picked was a Lanvin design he scooped up at Neiman Marcus last season. He added a black sable fur from Saks Fifth Avenue as her topper and accessorized with opera gloves. “She really is elegant, and she pulls this stuff off very well. She has such great posture.” And for loyal Alicia fans, there is much to learn from this look, Lawson noted. “When women do strapless gowns, they make the mistake of pulling it tight against the bust because they think that’s what’s going to keep it up, but really pulling it at the waist is how it keeps it up,” he said. “You see people on the red carpet with gowns smashed against their chest, when if you just pull it at the waist, it will help the fit better.” Tune in to see the classiest episode of The Good Wife tonight at 9/8c on CBS.
